No, the title of this post is not a mistake. Just in case you missed it, yesterday, March 14th (i.e. 3/14), was National Pi day.  This is the day we celebrate a very special number called pi which has over one trillion digits after its decimal point.

Circumference is the distance around a circle. Diameter is the longest distance from one side of a circle to another using a straight line. Pi is the ratio between a circle’s circumference and its diameter. Pi does not change no matter the circle which makes it pretty special.

Happy Belated Pi Day!
